Edit part 3: I still can't get to real world depths even with TL 10 and all the rules used.
Hmmm.

Is that an issue with the spreadsheet or with the pyramid article?

For what it's worth, according the the article, the Bathyscaphe Trieste should have dDR 4,733. At 59.5 feet long, it is SM +6, so the best armor available at TL 8 would provide dDR 5 per hull section. Even at TL 12^, the best dDR available per section is 20, or roughly 1/13 what is needed. I suspect the rules work fine for normal depths but things get whacky when taken to extremes.
